  • The test is not validated for rectal, pharyngeal or eye samples and the possibility of false positive and negative results may be higher with these sample types.
  • Visibly blood stained samples and heavily purulent samples are not desirable as these may lead to false negative results.
  • Urine samples from female patients are relatively insensitive and are not recommended.
  • Urine samples from patients using Replens vaginal moisturiser may give invalid or false negative results.
